Abstract: The present disclosure relates to, inter alia, devices, systems, and methods for use in the magnetic separation of biological entities from fluid samples. This device includes a magnetic separation chamber configured to receive a fluid sample for magnetic separation, where the magnetic separation chamber includes at least two magnets mounted on the surface or in the wall of the magnetic separation chamber. The device also includes a force provider configured to move the magnetic separation chamber in a side-to-side motion to mix and/or magnetize the fluid sample. In one embodiment, the magnetic separation chamber is in a form of a sleeve and comprises a substantially central channel for loading a vessel containing the fluid sample therein. The systems and methods of the present disclosure involve the use of this device to separate biological entities from fluid samples.

Abstract: A method for obtaining a point-of-collection, selected quantitative indicia of an analyte on a test strip using a smartphone involves imaging a test strip on which a colorimetric reaction of a target sample has occurred due to test strip illumination by the smartphone. The smartphone includes a smartphone app and a smartphone accessory that provides an external environment-independent/internal light-free, imaging environment independent of the smartphone platform being used. The result can then be presented quantitatively or turned into a more consumer-friendly measurement (positive, negative, above average, etc.), displayed to the user, stored for later use, and communicated to a location where practitioners can provide additional review. Additionally, social media integration can allow for device results to be broadcast to specific audiences, to compare healthy living with others, to compete in health based games, create mappings, and other applications.

Abstract: A diagnostic assay strip includes a first layer that includes an iron mobile labelled specific binding partner that will bind to and iron biomarker from a sample and produce an iron complex and a vitamin A mobile labelled specific binding partner that will bind to a vitamin A biomarker from the sample and produce a vitamin A complex. A second layer includes iron and vitamin A test regions, and a control region. The iron test region has immobilized specific binding partners that will bind to the iron complex. The vitamin A test region has immobilized vitamin A biomarker that will bind to vitamin A mobile labelled specific binding partner, which is not bound to the vitamin A biomarker, passing from the first layer to the second layer. The control region has a moiety which will non-specifically bind to and immobilize the iron and vitamin A labelled specific binding partners. Methods of using the diagnostic assay strip are also discussed.

Abstract: A method for characterizing an interaction between a first particle and a second particle is provided. The method includes the steps of: (i) providing an optical trap system including a photonics-based trap, a light source, and a camera; (ii) optically trapping, using the photonics-based trap, the first particle; (iii) obtaining a first measurement of a trap stiffness of the photonics-based trap; (iv) introducing the second particle to the optically trapped particle; (v) incubating the first and second particles under conditions suitable for an interaction between the first and second particles; (vi) obtaining a second measurement of the trap stiffness of the photonics-based trap after the incubation; and (vii) determining, using the first measurement of trap stiffness and the second measurement of trap stiffness, a property of the interaction between the first particle and the second particle.
